Short of serving store-bought ice cream, you won't find a simpler, more delicious dessert than this fruit cobbler. Use blueberries or strawberries. And if you use frozen berries, this dessert can be assembled in less than 10 minutes.
Adjust oven rack to upper-middle position, and heat oven to 350 degrees.
In pan put berries, 1 T sugar, 1 T honey, basil, and 2 T balsamic vinegar over medium heat and cook, stirring occasionally, for about 10 min or until berries are tender - but not mushy. Strain reserving liquid to drizzle over the cobbler once done.
Put butter in an 9 by 13 inch pan; set in oven to melt. When butter has melted, remove pan from oven.
Whisk flour, 1/2 cup of sugar, baking powder and salt in small bowl. Add milk; whisk to form a smooth batter - and no worries the batter will be quite thin. Pour 2/3 batter into pan, then scatter drained fruit over batter. Pour remaining batter.
Bake until batter browns and fruit bubbles, 60 to 70 minutes. Serve warm or at room temperature with a dollop of whipped cream or a small scoop of vanilla ice cream, if desired.
